What happens to pins when the MCU is not powered? Are the pins high impedance or do they sink current?

I'm using a MK10FN1M0VLQ12.

 

What happens to pins when the MCU is not powered and I would apply 3.3V to a pin? Are the pins high impedance or do they sink current?

 

I would need to be able to use the SPI also when the MCU has no power.
